Smart grids are the focus of major study today because of the necessity of modernization in electrical systems and reduction of greenhouse gas emissions that increases global warming. Reaching the best deployment method, you must first of all know the current electrical system and how to use them for the benefit of this new technology. Preparing the action plan we should be aware of the main points of smart grids in each step of the electricity system - generation, transmission and distribution. Analyzed these topics, this work will focus on the first step in the implementation of the smart grids: the smart meters, tool which is already being implemented in Brazil. The main characteristics and applications of these devices, as well as their communication structure with the core distributors will be showed during the paper. Finally, we present a case study which will be discussed and analyzed based in the results obtained with the implementation of smart meters in the city of Vancouver, Canada, where we have a considerable savings already in the first year, with fully paying the initial investment and still have a profit

The technologies are advancing at a pace so expressive that allow the increase of the power quality from generation until the distribution to end customers. This improvement has been made possible through the automation of the energy that follows to a better quality of the energy provided, a lower energy supply disruptions and a very short recovery time. The trend of today and the near future is the distributed energy generation. To keep the automated control of the chain, the presence of Smart Grids is needed and that will be the most efficient and economical way to manage the entire system. Within this theme, is going to be necessary analyze the electric cars that promise to promote a more sustainable transport because it doesn’t uses fossil fuels, and more healthy because it does not emit pollutants into the atmosphere. The popularization of this type of vehicle is estimated to happen in a few decades and the case study analyzing its influence on the demand of the electrical system is something that will be very important in the near future. This paper presents a study of the influence of the inclusion of charges refering to electric cars

This work presents a study about distributed generation using photovoltaic systems in the context of smart grids. The characteristics of a Smart Grid and the several aspects this concept involves - distributed generation among them - are discussed. There are also examples of equipment, like smart meters, and of national and international projects. The specificities of distributed generation and the rules and standards necessary in this sort of installation are talked through with focus in the solar energy generation method. Regarding photovoltaic systems, the working principles of the panels are presented, along with its main electrical characteristics and the technologies available. Finally there is a study concerning the sizing of a distributed generation system that involves photovoltaic panels in a residential plant. An analysis of the costs and return of investment period is made about the specific case in consideration.

The discussion of different themes revealed in the initial works of Merleau-Ponty, which are especially relevant in debates on the foundations of psychology, demands a closer look at the strategically complicity, from a psychological viewpoint, between The Structure of Behavior and the Phenomenology of perception. That context constitutes the background for this article. Based on the prerogative of this complicity, the goal is to present a reading that highlights primordial issues to outline the philosophical intention of that author. Despite the use of distinct methodological perspectives, both are part of one single work project. They fit into the discussion of Cartesian antinomies in philosophy and depart from the delimitation of the same problem, i.e. that of perception, as a point of integration between the two fundamental orders of Descartes’ thinking: the soul and the body.

The perception of modern society regarding the nature and indigenous peoples came to be shaped in the sixteenth and seventeenth centuries, with two major events, the invasion of Europeans in America and the scientific revolution. These events symbolize the cultural overlap and European thinking about the rest of the world. The current scenario is industrialism, consumism and cultural standardization driven by Cartesian thought. This work demonstrates, through literature research and data analysis, that this dominant model has caused the crisis of modernity, focusing especially on the environmental crisis that threatens human life. The solutions are present in the modern society the knowledge of indigenous peoples that is inherently ecological and sustainable by tradition. From the union of diverse cultures and knowledge dialog you can find solutions for today's problems and provide a renewal of relationships between modern society, indigenous peoples and nature. The World Conscious Pact presents this proposal which can be increased through public relations strategies in order to reconnect the man-nature bond, generating critical behavior with respect to the current dominant system and motivate society to adopt truly ecological postures. For this it is necessary to rescue the Earth image as a mother

The Literary adaptation for television miniseries are present in the schedule grids of Brazilian television channels. We can afford that it is about a line of production of the most relevant in the two main television networks that maintain a project of teledramaturgy. The Strong presence of miniseries imposes the need to investigate the process of intersemiotic translation from the literary text to the audiovisual text on the way to reflect the esthetics of these productions in front of the constants process of tecnology mutation. In this sense the goal of this research is to analize the book adaptation O canto da sereia for television, where we identify the discursivas strategies that structure the narrativity, the themes and the figures that enable the identification with the original literary text

This paper shows how the detailed examination of active and nonactive power components may produce new information for modern smart meters. For this purpose, a prototype of electronic power meter has been implemented and applied to the evaluation of the Conservative Power Theory (CPT). Considering five sorts of loads, under four different operating conditions, the experimental results indicate that the CPT is able to provide a good methodology for load characterization, which could possibly benefits consumers and power utilities in several different ways. The results also show that depending on the situation, the analysis of nonactive power terms may be more important than the observation of traditional power quality indices, such as total harmonic distortion, unbalance factors or the fundamental positive sequence power factor.
